To all whom it concern).-

Be it known that I, JOSIAH R. MoOoY, a

I citizen of the United States, residing at Marshalltown, in the county of Marshall and State of Iowa, have invented a certain newand useful Earth-Chipping Machine, of which .the followingis a-specification.

The object of my inventlonis to provide a machine de'si ned to be advanced over a field and provide with a rotary chipping device desigped to be rotated by an engine carried by t e frame andsaid chipping device pro vided with cutting blades designed to enter the earth and out out chi s or small sections of the earth and deposit t e same in the rear ofjtherotary chipper to thereby'thoroughly loosen and out up the ground into small :pieces and to leave the ground in the best possible condition for future cultivation and at the same time to cut up into small pieces sticks or cornstalks or similar devices lying upon the surface of the ground, so that said I articles will not interfere with the cultivation of theground.

A'further object is to provide means whereby the frame may be adjusted to cause the chipper to out 'more'or less deeply into the ground, and, further, to provide means whereby the chipper maybe reversed end for end and be caused to cut from the rear toward the front or from the front toward-the rear, asmay be found most desirable/inoperating on ground in different conditions. I 'My invention consists-in certain details in the construction, arrangement,-and combination of-the various parts of the device, where- 1 ,by the objects contemplated are attained, as

hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure l-shows a plan view of the complete machine embodying my invention. Fig.2 shpwsa side'elevation of same. Fig. 3 shows a detail side view of a modified form of rear 'supporting'wheel. Fig. 4 'shows a detail tary chipper-frame.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate the main frame of the machine, having at its forward end the axle 11, provided with the supporting-wheels 12 andhaving at its rear end the axle 13 with the supportingwheels 14. At the front of the frame isthe tongue 15, to which draft-animals may be attached and on top of the frame is the platform 16, upon the center of which is mounted a gasolene-e'ngine 17 ofordinary construction.-

Fixed to each side of the main frame 10, near its front, is an upright 18', and rotatably mounted in the tops of said .uprights is the shaft 19. On each end of this shaft is a pulley 20, to each of which a cable 21 is fixed. Said cable extends downwardly and passes under a pulley 22 on the main frame 10 and then upwardly and provided with a hook 23, for purposes hereinafter madeclear. l

Fixedly mounted on the shaft 19 adjacent to one of the uprights 18 is a hand-wheel 24, and slidingly mounted on the shaft 19 adj acent to said hand-wheel are two half-collars '25, each of which has a pin 26, designed. to

extend through the hand-wheel and into the upright 18, thus securelylocking the handwheel and shaft 19 against rotation, A s ring 27 is provided for normally holding the pins 26 in position in engagement with the upright 18; but I have provided for removing said pins from the upright 18 as follows: 28 indicates a cross-piece having a beveled edge and provided with a handle 29. Said beveled edge engages the parts 25, and.

chipping-blade, and 8 shows a section on 'line'8 8 of Fig. 1.

when the handle is turned it forces said parts to position for withdrawing the parts 26 and permitting the shaft 19 to freely rotate. By this arrangement of parts the hen wheel and its shaft are normally locked and may be released by means of the handle 29, so that the shaft may be rotated by the hand-wheel.

At therearof the frame lOon each side are two parallel uprights 30 to support the ro- This rotary chip erframe is composed of two sides, each of w 'ch is substantially the same, so that but one will be hereinafter described. This side' piece comprises a front member 31 to extend under the shaft 19 and to rest against the outer face of the upright 18 and between. the upright 18and a guard strap 32 onends.

said upright, which guard strap is provided with openings 33 to receive a limitingand'an outer portion connected at their forward ends and spaced apart at their rear The rear portion of the side piece of the chi per-supporting frame is formed of two hol ow members, the inner one, 35, being straight and having the inner portion of the 5 block is provided with a number of trans frame 31 telescopically connected with its forward end, and the outer member, 36, is spaced apart at its rear a'considerable distance from the member 31 ;'but its forward end is inclined inwardly toward the-member 35 and then forwardly, where the outer part of the member 31 is telescopically inserted in it.

The parts 35 and 36 are connected at their rear ends by the cross-piece 37 and also by a cross-piece 38, which extends entirely across the rear of the machine; The forward ends of the parts 35 and 36 are slidingl'y inserted in grooves-in a connecting-block 39, which verse openings 40, designed to receive a pin 41, which pin is passed through the uprights 30, so that said block is adjustably connected with the said uprights, and the parts 35 and 36 are'slidingly connected with said block and with the forward member 31.

The rear ends of the parts 35 and 36 are adjustably supported by means of an upright 42, having a longitudinal slot 43 to receive the cross-piece 37. This upright is bolted to the cross-piece by the bolts 44, so that it may be vertically adjusted relative to the crosspiece. At the lower end of the upright 42 is a supporting-wheel 45, designed to rest upon the ground-surface in the rear of the'rotary chipper, so that it will run on the level place out out by the chipper and always maintain the rearend of the frame at the proper elevation. from the ground-surface.

I have provided for supporting the rotary chipper as follows: Mounted upon the parts 35-and 36 in front of the cross-piece 38 is a supporting-bracket comprising a top plate 46, with two beatringboxes 47 on its upper surface and two openings on its under surface to receive the parts35 and 36. Extending downwardly from the plate 46 are two side pieces 48 and 49, with'the block 50 between them and having at their lower ends a bearing-box 51. A shaft 52 is mounted in the bearing-boxes 47 at both sides of the machine and 'has fixed thereto two sprocketwheels 53, connected by the chains 54 with the s rocket-wheels 55 on the engine-shaft, and ed to the outer ends of the shaft 52 are two sprocket-wheels 56, connected by the s rocket-chains 57 with sprocket-wheels on t e ends of the rotary chipper-shaft, as will appear hereinafter.

- inwardly at 72.

I have provided for throwing the engine into or out of driving enga ement with the shaft 52 as follows: On the hub of each sprocket-wheel 53 is a clutch member 58, and slidingly mounted on the shaft 52 adj a- 'cent thereto is a clutch member 59. Connected with each of said clutch members 59 is a bell-crank lever 60, fulorumed to the pin 61 and havin a link 62 pivoted to its inner end. Both of the links 62 are connected to a rod 63, havin a handle 64 and a rack 65, which rack is designed to engage a lug 66 on top of the engine, so that by operating this rod the clutches 59 ma be held in engagement with the clutch members 58 or in position out of enga ement.

The rotary chipper proper comprises a shaft 67, of approximately the same length as the shaft 52 and having fixed to its outer ends the sprocket-wheels 68, to be engaged by the chains 57. Near each end portion of the shaft 67 is a substantially disk-shaped cutter-head 69, and fixed to the center of the shaft is a supportin -disk 70. At one or more points (preferab y four) on each of the disks 69 and 70 is a fiat surface 71, and between these fiat surfaces-the disks are curved On each fiat surface 71 is a blade 73, to extend across the entire width of the machine from one of the disks 69 to the other. The cutting edge of said blade. 73

- projects outwardly over the cut-away portion 72, and adjacent to the outer end of each blade 73 is an edge-cutting blade 74, arranged parallel with the disk 69 and presenting a s arpened curved portion projecting beyond the cut-away portion 72 and inside of the blade 73. At the rear side of each blade 73 is another edge-cutting blade 75, to extend outwardly from the center of the-rotary cutter beyond the blade 73, and thus cut into the ground at the sides of the furrow being made. In some conditions of the soil it is desirable to use the rotary chipper in the form just described with only the four outshown in the modified form in Fig. 7. This modification comprises substantially triangular-shaped pockets 76, the outer edges of which extend from the rear of one blade 73 to the rear of the other and also extend the entire len th of the rotary chi per, so that earth cut oose by one of the b ades will fall into the adjacent ocket and be carried ar und until said poc ct stands in an inverted ppsition, whereupon the earth will be discharged from the pocket.

In the modified form shown in Fig. 6 the cutting-blade is composed of a cross-piece 77, having a series of sharpened blade-sections 78 riveted thereto. In thisform of the device if any of the blades should become the necessity of furnishing an entirely new blade extended across the entire cutter.

points 79, which In the modified form shown in Fig. these blade-sections are rovidedwith sharpened some conditions of the soil of the groun In Fig. 3 of the drawings I haveshown a device for reinovin clods of earth or the like from in front of t e supporting-wheels 45.

This device comprises an arm 80, fixed to the upright42 and'extended forwardly and then downwardly in front of the wheel 45, and at its bottom is-a fixed blade 81 to project forwardly in a plane slightly above the bottom of the wheel 45. 1

, In practical use and assuming the machine to be in the position shown in Fig. 2 of the drawings then the draft-animalsattached to j the tongue are caused to advance the machine overthe field and the engine is operated in a direction to rotate the lower cut-' ting-blades in a forward and upward direction. This will cause each blade in succession-to cut from the ground a chip or thin section extending the entire Width of the machine to points outside of the paths of the supporting-wheels 12 and 14, andthe chips or sections thus cut will be turned over by the blades and deposited in the rear of. the retary chipper, so that the round will be left lying in a thoroughly puverized and loose condition ready for forming a seed-bed without the necessity of using pulverizers, ,harrows, or other-implements. The blades 74 and 75 will cut off any sod or-roots orthe like, so that 'thechips or earth-sections will be easily removed from the ground at the edges, of the out being made. If it is desired to cause the rotary chipper to cut more deeply into the ground, the upright 42 is adjusted relative to; the rear end of the chipper-supporting frame, and the Windlass at the front of the main frame is also adjusted'to accomplish this result. 3 If it is desired to elevate the chipper. above the ground, this may be done by means of the Windlass at the front, which wilIcause the entire chipper-supporting frame to .be tilted upwardly at its rear end. The rotary chipper may also be adjusted forwardly and rearwardly bylmeans of the pins 41 in the openings 40. In some instancesit is desirable to operate the rotary chipper with the blades engaging the ground at the front and. moving downwardly and rearwardly to complete the out. When it is desired to do this, the shaft of the rotary chipper is removed and the chipper turned end for end and replaced in the frame. Then a reverse movement is imparted to the en gine and the blades will first strike on top of the ground and then cut downwardly and rearwardly. One of the advantages to be derived from this use of the rotary chipper is wi 1 be used to advanta e in that it will cut up stalks and roots and the like lying upon the top of the ground more method of procedure.
